Sažetak
The paper analyses the influence of the strain rate ranging from 10– 4 to 102 s– 1 on the material characteristics of formability of galvanized sheet, made of micro-alloyed steel with the yield point of 220 - 380 MPa and the thickness of 1 - 2 mm. The influence of the strain rate on traditional characteristics of cold formability, determined using mechanical and technological tests, as well as modified tests, is determined. The result of the paper is the determination of a critical strain rate, exceeding of which results in decreased cold formability of the tested steels. The paper responds to current demands from the practice, namely decreasing the weight and increasing the strength, the corrosion resistance and the productivity of cold formed products.
