Effects of different friction stir welding conditions on the microstructure and mechanical properties of copper platesAli Alavi Nia,Ali ShiraziDepartment of Mechanical Engineering, Bu-Ali Sina... with superior properties are produced when less heat is transferred to the workpiece during the welding process. It was also found that although the properties of the stir zone improved with an increasing......
the thermal cycling process. The particles in the welded joints become the source of failure under thermal cycling conditions[12-14]. The particles in the weld region were identified by means of EDS analysis... stress are induced under thermal load cycling conditions, which leads to dislocation glide. In the glide process, the blocking of the particles results in dislocation pile-up groups around these particles......
. At present, there is no thermal sensation evaluation method in the process of the establishing of human thermal equilibrium. In the human non-thermal equilibrium cold thermal environmental conditions...- regulation process of body. Considering of the thermoregulatory process, thermal sensation in the cold thermal environmental conditions is not only the function of thermal environmental parameters......
