This invention relates to a method for producing a magnesium light alloy product. In order to enhance formability in plastically forming a magnesium alloy material and obtain high tensile strength and high proof stress in the final product, the magnesium alloy material is cast by using molten magnesium alloy containing strontium of 0.02 to 0.5 weight percent and then plastically formed into a magnesium light alloy product in set shape.

A method for manufacturing an apex seal for a rotary piston engine comprising steps of preparing an apex seal blank made of ceramic material, and applying a high energy heating radiation to the sliding surface of the apex seal blank to form a roughened and porous structure on the surface portion of the apex seal blank. The high energy heating radiation is desirably applied to the apex seal blank under a non-oxidizing atmosphere so that an oxidization of the components of the ceramic material can be prevented.
