Aluminium alloys are widely used in many industrial applications including automobiles and aeroplanes, on account of their light weight. However, the wide-spread use of such alloys was contingent on the discovery of precipitate strengthening as a means for improving the tensile properties of these alloys necessary for most applications. Discovered over a hundred years ago, the technique involves heating alloys to elevated temperatures, which allows nanoscale secondary phases to precipitate in the metal. These precipitates hinder dislocation motion throughout the material and greatly increase their tensile strength. Now, however, Australian researchers led by Christopher Hutchinson at Monash University have developed a room-temperature cycling technique that reproduces and improve...

3-D printing is an unstoppable force. Not too long ago, the printing speed and limited output of 3-D printers made them suitable only for rapid prototyping. But in the coming years, 3-D printers will be at the heart of full-scale production capabilities in several industries, from aerospace to automotive to health care to fashion. Manufacturing as we know it will never be the same.

In the development of modern cutting tool materials, cemented carbides play a leading role. Moreover, the performance of other cutting tool materials also improves remarkably, the applying field expanded, forming unique advantage and the overall pattern of complementary applying field to each other. The rapid and comprehensive development of cutting tool materials has laid the foundation of high-speed and effective cutting process.
