Now-a-days turning of hardened steel over 45 HRC is an emerging technology replacing grinding operation for finishing the components. Multilayer coated carbide insert being an inexpensive cutting tool material has less researched in machining hardened components. Thus, the objective of the present work has been set to have a study on hard turning of EN 31(More)
In this paper, self-heating of a state-of-the-art SiGe:C BiCMOS Heterojunction Bipolar Transistor (HBT) is studied by means of 3D thermal TCAD simulations. Steady-state, large signal and small signal transient simulations are performed on different device structures to investigate the impact of backend layers on thermal impedance (Z<sub>TH</sub>).
