In cold isostatic pressing, the mold is most typically made of which one of the following: thermosetting polymer tool steel sheet metal textile rubber

Hot isostatic pressing can be done without a can to get rid of porosity, but what needs to be done before the hot isostatic pressing to make the can unnecessary?

A bearing of simple geometry is to be pressed out of bronze powders, using a compacting pressure of 240 MPa. Outside diameter of the bearing 45mm, inside diameter 20 mm, and length 18 mm. What is the required press tonnage to perform this operation? Whole number answer.

1-In hot forming processes, the strain rate is important since deformation resistance of w.p. increases as is increased. ****** 2-The coating of interior surfaces of casting molds can aid....... 3- Based on nature of use, the cores can be classified into: 1. and 2. ..... and 4-In centrifugal casting, fine grain microstructure (resisting to corrosion, better mechanical properties) castings can be obtained because of...... 5-During manufacturing processes, the residual stresses can be arising due to three major reasons: 1......, 2...... and 3...... 6- The wheels, pulleys and flywheels can be manufacturing by...... casting. 7- The ...... of casting molds can help removing impurities and facilitating metal flow inside the molds. 8-In horizontal true centrifugal casting, a tubular products having uniform wall thickness can be obtained when...... is greater than ......

4) List the passageway (gating system) elements in sand casting moulds and show them with drawing? Draw the stress-strain curve and gives the stress and strain equations for both Engineering and True stress-strain

d) A common process for the assembly of compound cylinders is thermal shrink- fitting. In your own words, Describe briefly how this procedure may be performed. Explain with reference to solid mechanics concepts, how a thermal shrink-fit can generate forces which hold the cylinders together and enable higher pressure bearing capability (in comparison to a single cylinder). Considering the concepts/principles explained above, describe more generally an alternative method for achieving such improved performance and describe advantages/disadvantages, if any, over a thermal shrink-fitting procedure. (200 - 300 words).

QUESTION 3 Extrusion and drawing have numerous application in manufacturing continuous as well as discrete products from a wide variety of metals and alloys. There are three types of extrusion. Please describe and draw the schematic illustration to represent each of them.           Question 4 Selection of die in forging process is very important in order to control the quality of the product. List four general requirements for die material.

4. A steel rotor of a gas turbine of 400mm outside diameter, 150mm inside diameter and 25mm thick is shrunk onto a solid steel shaft. At its service speed of 3000rev/min the radial stress on the outside of the rotor is 1.45MPA. Determine the shrinkage allowance required in order to avoid failure, if the design stress limit of the material is 200MPA. For the material assume a Young's Modulus, Poisson Ratio and density of 210GPA, 0.3 and 7850k g/m3 respectively.

The table provided is table 10.1, therefore table 10.1 and table 5.1 are the same table. Please show all your work. :D thank you

The parting line in injection molding is which one of the following: O the lines formed where polymer melt meets after flowing around a core in the mold the narrow gate sections where the parts are separated from the runner where the clamping unit is joined to the injection unit in the molding machine O where the two mold halves come together
