Version 12.4 (January 2021)

BUG FIXES

• fixed missing temperature line in QForm export file

Version 12.3 (December 2020)

*UPDATES FROM VERSION 12.2 to 12.3 are only necessary for Cu alloy users*

BUG FIXES

• fixed calculations for Cu alloys failing (introduced in 12.2)

Version 12.2 (November 2020)

NEW FEATURES

• in steel solidification/quench properties graphs, added a note about whether secondaryphases were included or not
• steel TTA calculation: homogenisation temperature calculated when relevant
• export to COMSOL Multiphysics for steel heat treatment

BUG FIXES

• fixed quench properties/welding cycle/advanced TTT calculations failing when running with K or F as temperature unit
• fixed choice of old/new format in Sysweld export
• fixed a bug in cooling curve calculations which can lead to erroneous results if a minor phase appears before a major one
• fixed possible failing calculations in Advanced TTT when the chosen temperature unit was K or F

Version 12.1

BUG FIXES

• corrected a bug preventing calculations of "Quench Properties" being made for multiple cooling rates when secondary phases were included
• fixed double inclusion of Scandium in the list of elements for Al alloys. This created problems of saving the right composition

Important: this fix for Sc means that files with the wrong compositions may have been saved if you have used version 12.0 for Al alloys including Sc

• To correct this:

• a) Install version 12.1 or above

• b) When JMatPro® starts, look into the DOS shell and it will say JMatPro® will run in xxx. This will give you the base folder where files are stored. Close JMatPro® and in this base folder, find the inits/elts.ini file. Delete this file

• c) In "File->Load Material File" delete all mat files created in version 12.0 for which there is Sc in the alloy composition

• d) In "File->Load Composition" delete all compositions saved in version 12.0 for alloys which should contain Sc

•
