Friction Bit Joining (FBJ) is a recently developed spot joining technology capable of joining dissimilar metals. A consumable bit cuts through the upper layer of metal to be joined, then friction welds to the lower layer. The bit then snaps off, leaving a flange. This research focuses on FBJ using DP980 or DP590 steel as the lower layer, AZ31 magnesium alloy as the top layer, and 4140 or 4130

Joining of 2024 Aluminum Alloy Stud to AZ80 Magnesium For its potential usefulness for weight reduction, an advanced high-speed solid-state joining method was tested for its applicability to the joining of 2024 aluminum alloy studs to AZ80 magnesium alloy extruded plates. In this method, a stud having a circular projection at its bottom is pressed against a plate surface, whereupon a discharge
Joining of Cf/SiC Ceramic Matrix Composites:A ReviewThe joining temperature is high, the CTE and elastic modulus of the composites and metals are mismatch, and it is easy to induce high residual stress. Due to sharp structural transition near the interface and the lack of a buffer layer to relax the stress, the residual stress is high enough to lead to a lower joint strength.

Properties and automotive applications of advanced high Advanced high-strength steels (AHSS) are a class of steel used primarily in sheet form for automotive structures. The microstructures of the types of steel in this classification were initially multiphase, with ferrite as the dominant phase; however, grades introduced more recently have been fully martensitic or based on austenite. This chapter initially introduces the requirements of an
