... in shrinkage and densification. Fig. 8.1 Scanning electron micrograph of spherical bronze particles undergoing early-stage sintering, as evident by the growth of necks between the particles Sintering—strengthening from heating—was first applied to ceramic pottery-making 26,000 years ago. Today...

..., and/or molybdenum. The preferred use of powder mixtures rather than of prealloyed powders is due to several factors: The most important factor is that elemental powder mixtures generally possess significantly higher compressibilities than their prealloyed counterparts. Powder mixtures are usually less...

However, metal powders sometimes are sintered without compacting, which is called “loose powder sintering.” This process is suitable for certain specialized PM applications such as bronze filters and porous electrodes. Sintering time and temperature are the most significant factors...
