摘要： The method of preparing an adhesive layer on a substrate includes introducing a thermally reactive powder comprising aluminum and a second metal into a plasma torch, wherein the thermally reactive powder is substantially free of binder, additive and contaminant and does not contain a significant amount of intermetallic compound into a plasma torch. An exothermic reaction is initiated within the thermally reactive powders in the plasma torch and the exotherming powders impinge onto a substrate, such that the heat generated by the exothermic reaction is generated predominantly on the substrate.

摘要： The present invention utilizes a dynamically controlled frequency system for the process of induction heating semi-solid material. Semi-solid precursor material is machined into billets of a desired size. These billets are subjected to one or more heating processes utilizing an induction heating process that is dynamically controlled by adjusting the frequency of an induction coil current to achieve a desired temperature in a semi-solid material billet.

摘要： There is provided a continuous casting and rolling process for continuously producing a deformed fine grain solid metal composition suitable for semi-solid forming. The process is characterized by high throughput, continuity, and precise control of the process parameters, such as solidification rate, rolling temperature and speed and total deformation. The solidification rate is preferred to be in a range of 10 to 150° C./s, and the total deformation is controlled to be larger than a Mises effective strain of 2.3 to obtain a deformed fine grain structure with enough distortion energy. A method combining the continuous casting and rolling process of preparing semi-solid raw material with semi-solid forming of shaped articles is also disclosed.

摘要： There are provided a continuous frictional extrusion process for continuously producing a deformed fine grain solid metal composition suitable for semi-solid forming. The process is featured by a large range of produce dimension and by precise control of the process parameter, such as total deformation, extrusion temperature and speed. The total deformation is controlled to be larger than a Mises effective strain of 2.3 to obtain a deformed fine grain structure with enough distortion energy stored, having a grain size less than 30 .mu.m and a subgrain size less than 2 .mu.m. A method combining the continuous extrusion process of preparing semi-solid raw material with semi-solid forming of shaped articles is also disclosed.
