In some occasions, you will have to write an essay in the extremely short amount of time on the exam in college or high school. Also, you may be a little bit of a procrastinator, and find yourself in a situation when the paper is due tomorrow morning, and you have not even chosen the topic yet. Even though a last-minute essay cannot look as great as a work prepared successively and carefully within the whole time given, you still have a chance to submit a decent paper. The working process will require your full attention and a lot of effort, even if you are assigned a simple essay. However, if you learn the next few tips, the essay writing will seem significantly easier and feasible even when you are short on time.

Firstly, clean up your working space to get started. Make sure you have everything you need on the table, take a pen, a few sticky notes, your laptop, and read through the assignment requirements. In case no prompt is given, search for good essay topics, and pick a few uncommon and interesting ones you will be able to write about. Making a final choice, think which topic is the most relevant to your current studies and will not take too much to research.

Afterwards, look for the most trustworthy sources or the ones you are certainly allowed to use. If you are not sure, access the online library or any free services where you can look for the books and articles for your essay. Use sticky notes to write down the information and put them in front of you to see how much data has been gathered and if you need to continue researching. Reread these notes from time to time and cross out the info you do not find relevant anymore.

When you have the data you need to produce a quality work, it is crucial to think about the structure of the future paper. If you are not sure how to write an essay outline properly, check what your essay type is first. Each type is organized differently, so you need to look up the structure every time you are given an essay homework. You can also search for an example of the essay on your topic, and adhere to its outline. No matter what kind of essay you are going to write, it is important to start with a thesis statement. It should declare what problem you will review in the paper, and which facts or arguments you will use to do it professionally. As these arguments will be discussed in the main part of the essay, outline the body paragraphs and put down a few sentences with the rough description of each paragraph. Think of the way you will engage the reader in the introduction, and which thought will be conclusive for the paper. When the direction of the work is clear from the outline, use it to draft the first version of the essay.

If you are not used to model essay writing, do not worry - your draft should not necessarily look like a masterpiece. It is only the depiction of your thoughts, and as you will have them written down, it will be easier to create a good essay. There is no best way to write an essay, so trust the working methods you usually use. You may like taking short breaks once in a few minutes, or write everything in one sit - just make sure to keep the focus on writing and avoid the urge to call a friend or watch something online. Thus, you will finish the paper faster, and will not feel guilty for engaging in other activities afterwards.

Do not forget to go through the essay a few times after the completion. Everyone makes typos and mistakes by accident, but it is about you to find and fix them before your teacher does. If you need help with an essay editing, try asking a friend or a family member to read and analyze your work. Also, you can order editing services in case your paper needs to be perfectly polished so that you can submit an ideal essay and get an excellent grade.

As these steps are simple to follow, you will not have any problems coping with an essay on time. Try the whole procedure at least once, and you will not have to use any other tips preparing an essay paper during your studies!

What is the maximum eutectic temperature of Aluminium silicon alloys?

577 oC.
Aluminium-silicon alloys form a eutectic at 11.7 wt% silicon, the eutectic temperature being 577 oC.

What is the maximum solubility of Si to Al?

The maximum solubility of Si in Al is ~1.65% at 577 °C, and the solubility decreases with decreasing temperature. There is virtually no solubility for Al in Si at any temperature to the melting point. a finer eutectic particle spacing.

What is Al-Si?

Al-Si alloys differ from our “standard” phase diagram in that aluminium has zero solid solubility in silicon at any temperature. This means that there is no beta phase and so this phase is “replaced” by pure silicon (you can think of it as a beta phase which consists only of silicon).

What is Hypoeutectic Al-Si alloy?

The hypoeutectic Al-Si based alloys are well-known casting alloys with a highly desirable combination of characteristics, such as castability, weldability, low thermal expansion coefficient, good corrosion resistance, and machinability.

What is the eutectic composition of Al Si system?

ADVERTISEMENTS: Al-Si diagram is a eutectic diagram where solid solubility at least of aluminium in silicon is negligible, and maximum solubility of silicon in aluminium (at eutectic temperature) is 1.65%. The eutectic composition is 12.7% silicon.

What is the fusion temperature of aluminium silica?

The aluminium silicon alloys form a binary eutectic at 11.7% silicon with a melting point of 577 °C, the two phases being solid solutions of silicon in aluminium, 0.8% maximum at room temperature, and aluminium in silicon. There are no intermetallic compounds.

What do you mean by eutectic temperature?

Eutectoid: Eutectoid refers to a homogeneous solid mixture that forms from cooling two or more melted metals to a certain temperature. Eutectic Temperature or Eutectic Point: The eutectic temperature is the lowest possible melting temperature for all of the mixing ratios of the component substances in a eutectoid.

What is eutectic point in chemistry?

freezing point of liquids In phase: Binary systems. This point is called the eutectic. It is the lowest temperature at which a liquid can exist in this system. At the eutectic, both anorthite and titanite crystallize together at a fixed temperature and in a fixed ratio until the remaining liquid is consumed.

What does silicon aluminium do?

Silicon (Si) 4xxx – The addition of silicon to aluminum reduces melting temperature and improves fluidity. Silicon alone in aluminum produces a nonheat-treatable alloy; however, in combination with magnesium it produces a precipitation hardening heat-treatable alloy.

What is hypoeutectic and hypereutectic?

If an alloy is not of eutectic composition then it is either hypereutectic or hypoeutectic. If the alloys’ composition places it to the left of the eutectic point on a phase diagram, then it is hypoeutectic. If it is to the right of the eutectic point then it is called hypereutectic.

What is a hyper eutectic alloy?

A hypereutectic alloy is metallic alloy with a composition beyond the eutectic point. A typical alloy may have a substrate and a primary alloying element.

What is eutectic material?

(A eutectic or eutectic mixture is a mixture of two or more phases at a particular composition of materials that have the lowest melting point, at which temperature the phases will simultaneously crystalize.

What is the solubility of Si in Al at eutectic temperature?

The maximum solubility of Si in Al occurs at the eutectic temperature and is 1.65 wt. %. At least up to the late 1950’s, the eutectic was believed to be at 11.6 wt. % Si. Modification of the eutectic by very small Na additions has been known since the 1920s3-5.

What is the melting point of Si and Al at different temperatures?

The melting points of Al and Si are, respectively, 660.45 and 1414 °C, while the eutectic reaction occurs at 12.6 wt. % Si and 577 ± 1 °C2. The maximum solubility of Si in Al occurs at the eutectic temperature and is 1.65 wt. %. At least up to the late 1950’s, the eutectic was believed to be at 11.6 wt. % Si.

Is the eutectic mixture (Alpha+Si) mainly alpha?

The eutectic on this phase diagram contains much more alphathan Siand so we expect the eutectic mixture (alpha+Si) to be mainly alpha (consider the lever rule at the eutectic temperature).

What is the difference between primary Si and eutectic mixture?

The primary Si has a cuboidal form which can be seen in the micrograph. The eutectic mixture, though, is non-lamellar in form and appears, in section, to consist of separate flakes (although studies have shown that the flakes are, in fact, interconnected three dimensionally).
