Abstract In this thesis, LIBS has been utilized to determine the elemental composition of metal samples by forming micro plasma on the surface of a ten specimens from unknown standard steel alloy. LIBS and ICP methods were used for detecting elemental analysis of alloys. Laser hardening is a method of heat treatment of alloy steel depends on the potentiality of laser as heat source of high rapid heating rate occurring phase transformation on the heated surface |
