Boutique Hollister Montreal,Cloth0683,transformation of the metastable amorphous phase
Surface profilometry can be used as a wear measurement technique on components too cumbersome for weight loss methods. Engine cyclinder-bore wear is estimated from the bearing length ratio parameter computed from axial profiles of the cylinder-wall. The system approach is used to Hollister Toronto Eaton Centre provide insight to the impact of piston ring forces on cylinder-bore wear. New and worn values of arithmetic average roughness and bearing length ratio parameters for each of three case studies representing 12, 31 and 700 operating hours are presented. Estimates of radial wear for typical internal combustion engine cylinder-bores are included
The crystallization and decomposition of vacuum-deposited amorphous silicon-aluminium films have been examined by means of transmission electron microscopy. Depending on the aluminium concentration, the transformation of the metastable amorphous phase into the stable phases of aluminium and silicon proceeds by different reactions such as pre-crystallization of aluminium, polymorphous transformation into supersaturated crystalline solid solutions or eutectic decomposition. The temperature dependence of the eutectic crystallization was measured. The results are discussed in terms of the thermodynamics of amorphous-to-crystalline transformation.
