摘要：

The technology of heat forming of powder products with lengthwise grooves has been developed, which consists of pressing the working elements of a tool in the body of a preheated porous blank. The influence of porosity, shape, the degree of preliminary plastic deformation, and the geometric parameters of the porous blank on the area of the textured zone of product lugs has also been examined. The maximum values are attained when blanks with a porosity of 15% (without preliminary compression) and 20–25% (with compression) are used.
