In the examination to replace machined-steel parts with lightweight composites.

In the examination to replace machined-steel parts with lightweight composites, automakers have been working onward metal-matrix composites, which are made at filling molds with powdered metal and then applying high squeezing These composites can be produc quickly, at a fraction of the richness of conventional, machined-metal parts. The confidence is that one day these materials would be used for uniform the most demanding engine applications, so as connecting rods.
However, the technology solely works if the powdered metal can liquefy readily through a feeder
