- (a) Powder metallurgy (PM) is a net-shape forming process by which fine powdered materials are blended, pressed into the desired shape (compacted), and then heated (sintered) in a controlled atmosphere to bond the contacting surfaces of the particles and establish desired properties. i) Justify the reasons why powder-metal parts are commonly used for machine elements which requiring good tribological characteristics. ii) Compaction is the step in which high pressure is applied to the powders to form them into the desired shapes. The purposes of compaction are to obtain the required shape, density, and particle-to-particle contact. In your opinion, is there any density variation in the compacting of powders? Justify your answer. If your answer is yes, propose appropriate methods to reduce the variation.arrow_forwardA technician measures the pressure at 4 locations along a natural gas pipeline, but the gauges at each site use different units. Compare the reported values to determine whether all the pressures are equivalent or whether one site has a pressure different to the others. (Note the choices below may be given in 'exponential' format, e.g. 1200000 = 1.2x106 would be displayed as 1.2e6) Pressure conversion factors are given in the Module 3 Useful Data page.
