1.The alloy of Mo+30% W is susceptible to hot brittleness at 1400–1800°C.2.Varying the tungsten content from 28 to 35% has little effect on the susceptibility to hot brittleness. Raising the carbon content from 0.002 to 0.007% sharply reduces the reduction in section in the hot brittleness range. The addition of a small amount of hafnium (~0.2%) to the Mo+30% W alloy reduces susceptibility to hot brittleness.3.Increasing the strain rate within the limits of 0.5–3000 mm/min reduces susceptibility to hot brittleness.4.The hot brittleness of the alloy is due to precipitation of phase of the Mo2C type in the grain boundaries. |
