This paper details tests on steel-wood-steel connections with thin dowels carried out at the University of British Columbia in Vancouver, Canada. Connections configurations were selected in such a way that the influence of the main parameters such as dowel slenderness ratio, dowel strength, fastener spacing and end distance and the number of dowels could be studied. An important issue of the pa...

According to the ATEX directive, any personal protective equipment or work intended be used in a potentially explosive area must made of materials that cannot source mechanical static electricity-related sparks. The carbon steel is one most widely metallic materials, but possibility using it manufacture environments low. Therefore, purpose this article present an alternative solution use metal ...

The reduction of cost in the process of iron manufacture is of permanent interest in steel-making industry. An important part of the overall cost in the process of iron manufacture is the cost of production of metallurgical coke. This problem is solved by finding a new technologies of iron production (COREX) or optimization of current ways of iron production. Therefore we have adopted the metho...

As the turbine industries need to manufacture turbine blades made of martensitic stainless steel AISI 420 with high toughness and wear resistance, local laser hardening has become more and more important. In this research, surface of the samples was initially hardened by high-power pulsed laser beam; then, optimum parameters of hardening were calculated and wear resistance of surface hardened s...
