本实验室进行研制的微波管,要求采用直径约1吋,壁厚约0.05吋的短管状部件。圆环之类的部件可以用钼管或者钼棒加工而成,而钼管或者钼棒则不易加工。由于这种原因,便考虑用板材来深引伸厚壁杯体。钼是压力加工中最难加工的材料之一。市场销售用的钼是用粉末冶金制造的,在室温下,延性非常差。 Microwave tubes developed in our laboratory require short tubular parts about 1 inch in diameter and about 0.05 inches in wall thickness. Components such as rings can be machined from molybdenum tubes or molybdenum rods, while molybdenum tubes or molybdenum rods are not easy to machine. Due to this reason, it is considered that the thick-walled cup body is deeply drawn with a plate. Molybdenum is one of the hardest materials in pressure processing. The molybdenum marketed is made from powder metallurgy and has very poor ductility at room temperature.
