Summary
In subject the students will be acquainted with metals formability which is an important attribute from point of view of technological design. Deformation limits and production costs are determined by metals formability. In subject the students will be acquainted with influence of forming upon properties and structure of materials, basic laws of plastic deformation and metals formability. In subject the formability is defined as a property of material, theoretical base of formability will be described. The most important processes variables will be appointed and criterii for formability evaluation will be prescribed. The primary and specialized tests for workability will be presented for cold, warm, super plastic and hot metal forming, for bulk and sheet metal forming.
