The newtons law of cooling for convection heat transfer process? An alloy of overall composition, X B = 0.7 was equilibrated at temperature T 1 . Microstructural analysis showed two phases, (α and β, and that the phase fraction of β was 0.75. Given that the equilibrium composition of β at Ti is 0.9 as shown in the phase diagram below, the maximum solubility of B in α (in mole fraction) at this temperature is . . . . . . . . Determine the correctness or otherwise of the following Assertion [a] and the Reason [r] . Assertion: In a pure metal weld, elastic modulus in the heat affected zone (HAZ) is the same as that in the base metal. Reason: Coarse grained microstructure in the HAZ results in lower hardness. A glass reinforced polymer composite comprises of 35 volume % glass fiber and 65 volume % of polymer resin. The elastic moduli of glass and polymer resin are respectively 70 GPa and 3 GPa. The elastic modulus of the composite (in GPa) under iso-strain state is Which of the following method is used to produce powder in powder metallurgy?
