Both strong and light materials are usually needed in order to meet this demand.
For example, the compressor disk can be made into dual alloy disk (DAD) with higher strength and lighter weight materials [1-3].

Study on the differential thickness ratio effect on formability of TWB based on numeric simulation Xue Song 1,2, a, Zhou Jie 1,b 1 College of Material Science and Engineering, Chongqing University Chongqing, China 2 School of Manufacturing, Southwest University of Science and Technology, Sichuan, China a xuesong2004@126.com, ba65105410@cta.cq.cn Keywords: tailor-welded blank; differential thickness ratio; numeric simulation; square box Abstract.
Introduction Tailor welded blanks (TWBs) are composed of more than two materials with similar or different strengths or thicknesses joined together to form a single part before the forming operation.
The material type of punch, die and blank holder choose rigid material.
The material type of sheet chooses elastic-plastic material and adopts Belytschko-Tsay shell element.
The parameters of the two materials are shown as Table1.

The tribo corrosion is associated with the degradation of the materials when the effect of wear and corrosion are combined simultaneously [6].
