Homework Answers
1. true (as it can be observed slope of 3 is more than 1 at colling phase)
2 . Fales (as for faster colling grain growth rate is lesser)
3. False ( as shown in the figure if goes to lower banite )
4. true ( as it fall into martensite which is needle shape )
5. true ( as it yeild fine banite which haver higer stegth than 2 which yield course perlite )
6. Fale ( as it is banite can be seen from figure )

HEAT TREATMENT OF STEELS EXPERIMENT 6 EXPERIMENT 6 HEAT TREATMENT OF STEELS THEORY The Effect of Cooling Rate One of the most convenient methods for controlling the properties of a given steel, i.e., a steel whose composition is already fixed, consists of austenizing the steel and ten cooling to room temperature at some predetermined rate. A variation of cooling rates...

1. Circle whether the following statements are true (T) or false (F). (2 mark each, total: 32) I F Substitutional atoms replace the solvent atoms in a unit cell F F Increasing grain size will increase the yield strength. F Growth of a phase is a thermally activated process. T F Spheroidizing results in coarse precipitates. TF Hot working requires less energy for plastic deformation than cold working F F A eutectoid reaction can be written as: Le Solid 1...

please answer question 2,3,4
A critical feature of steel is that a considerable amount of carbon can be dissolved in the austenite, phase, (up to 2.14 w/o at 1147"C), whereas carbon is essentially insoluble in ferrite, Cooling from point d to e, just above the eutectoid but still in the an increased fraction of the +y region, will produce phase and a microstructure similar to that shown: the particles precinitates out in the form af an intermetallic.compound called iron-carbide...

1. Consider the three molecules below to answer the following questions. Circle TRUE or FALSE at the end of each question (0.5 points each). Molecule A Molecule C Molecule B A. The rate of EAS with Molecule B will be faster than the rate of EAS with Molecule A (assume MAJOR product formation). TRUE or FALSE B. Molecule C will undergo nitration to yield a meta-product that is the MAJOR product. TRUE or FALSE c. The rate of meta-product formation...

1 Check if the statement is true (U) or false (F). (3 point each, total 30 points) 1) Material properties can be changed through alloying, processing, and heat treatment. Alloying is during material production, processing is during manufacturing or material shaping, and heat treatment can be done any time without changing the shape. (T , F) 2) Finer grain of the crystalline materials makes material stronger. ( T F ) 3) During punching process, high clearance between the punch and...

This case presents two phases of a large business transformation project involving the implementation of an ERP system with the aim of creating an integrated company. The case illustrates some of the challenges associated with integration. It also presents the obstacles facing companies that undertake projects involving large information technology projects.
