HIGH-FORMABILITY STEEL PLATE WITH A GREAT POTENTIAL FOR STRENGTH ENHANCEMENT BY HIGH-DENSITY ENERGY TREATMENT
摘要
Disclosed are alloying elements and microstructures suited for realizing a marked increase in strength of low-carbon or ultra-low-carbon steel plate using a high-density energy source such as a laser. Steel blanks satisfying both high formability and high strength requirements are provided which show sufficient press formability and yet can be markedly increased in strength by laser treatment or which have been markedly increased in strength by laser treatment in areas not to be subjected to severe forming. <IMAGE>
