[Cbe-grads] FW: Special Colloquium (10/5): Dr. Sinn-wen Chen, Understanding Peculiar Material Behaviors through Phase Diagrams

[Brunelli, Nick]

Dear all,
  The MSE department will have a special seminar by Professor Sinn-Wen Chen on Thursday (10/5) at 10 – 11 am in Scott N0048.

  As his colloquium title indicates, he will be discussing phase behavior of materials.

Sincerely,
Nick





Special MSE Colloquium



Understanding Peculiar Material Behaviors through Phase Diagrams



Sinn-wen Chen

Department of Chemical Engineering,

National Tsing Hua University, Hsinchu, Taiwan



Date/time: Thursday, 10/5, 10:00-11:00 a.m.

Location: Scott Labs N0048<https://odee.osu.edu/scott-lab-n048>



Abstract

Various peculiar material behaviors are observed. Ag-5wt.%Sb solder, with a melting point of 240°C (ranging from 245°C to 240°C), melts at 230°C. Unexpected Ag and Cu whiskers form and grow rapidly in annealed Ag-Cu-Te alloys. The reaction rates in Sn-Pb/Fe are faster at lower temperatures. These peculiar behaviors can be understood by examining their respective phase diagrams.
