HTi, LTi, HTi-Mo and LTi-Mo Steels

Steel name: HTi, LTi, HTi-Mo and LTi-Mo
Diagram No.: 5355
Type of diagram: DCCT
Chemical composition in weight %: See the table.
Steel group: Bainitic steels
Note: New industrial material was produced in the lab to make it possible to study synergy of Ti and Mo. This was done by making two base alloys with different levels, i.e. low (LTi) and high titanium additions (HTi). Above the base material also steel alloyed with Mo was investigated. The material was heat treated, hot rolled and machined. The laboratory melt were cast in 2 kg: s ingots with dimensions 40*40*100 mm. The ingots were hot rolled to break down the cast structure and for homogenisation to 8-10 mm. The dimensions of the dilatometer samples were 4 mm in diameter and 8 mm in length. Dilatometric tests were made and DCCT-diagrams established according to the following test procedure:
- DCCT on HTi, LTi, HTi-Mo and LTi-Mo
- Cooling rate - 1s,5s,10s,20s,30s,45s,60s,85s,100s,150s.
- Deformation from 8 to 3.7 mm.
- Hardness measurements (1 kg) on all dilatometric DCCT samples.
