A) What is the specific heat of titanium in J/ (g*degrees C) if it takes 89.7 J to raise the temperature of a 33.0 g block by 5.20 degree C ? Which material has the lowest specific heat capacity? Metals such as iron have low specific heat. It doesnt take much energy to raise their temperature. Thats why a metal spoon heats up quickly when placed in a cup of hot coffee. Sand also has a relatively low specific heat. Deformation is about 50% below the recrystallization temperature, followed by conventional aging treatment. You must keep in mind that the specific heat capacity of a substance is affected by the temperature and Figure 1 Schematic diagram of the annealing temperature range of various methods in titanium alloy. As the obstacles to the movement of the grain boundaries disappear, the grains grow up sharply, with an average diameter of about 300 m, as shown in Figure 5(d). Submit Answer Try Another Version 3 The mechanical properties of titanium alloys largely depend on the proportion, morphology, size and distribution of these two phases. Figure 5 is the microstructure of TC21 alloy at different solid solution temperatures. (7) When heating in the phase region, grains tend to grow larger.

Economics Engineering This feature is different from the martensitic phase transformation of steel, where the heat treatment strengthening of titanium alloys can only rely on the aging decomposition of the sub-stable phase (including the martensitic phase) formed by quenching. Applications and Design This energy breaks down the attractive intermolecular forces and must provide the energy necessary to expand the gas (the pV work). Commonly used are annealing treatment, aging treatment, deformation heat treatment and chemical heat treatment. Compared with other issues, this issue has better plasticity, fatigue strength, notch sensitivity, and thermal stability, but its fracture toughness, durability, and creep strength are worse. The time required depends on the cross-sectional size of the workpiece, processing history and the degree of stress relief required. The specific heat of carbon steel is 0.49 kJ/kgC and the heat required can be calculated as, q = (0.49 kJ/kg oC) (2 kg)((100 oC) - (20 oC)). Instr. W. E. Forsythe and A. G. Worthing, Astrophys.
