Influence of Ti and V on the hot ductility of high manganese austenitic steel

工程科学学报, 2017
The influence of Ti (mass fraction 0.10%) and the joint additions of Ti (mass fraction 0.11%) and V (mass fraction 0.20%) on the hot ductility of as-cast high manganese austenitic steels were studied using a Gleeble-3500 thermo-mechanical simulator over ...

Self‐Seeded Nucleation of PET in a Benign Solvent Yields a High Modulus Aerogel With Ultra‐Low Thermal Conductivity

Advanced Materials, EarlyView.
A new benign solvent (1,3‐diphenylacetone) enables a simple, safe, and sustainable dissolution and gelation method to convert waste PET into low density, monolithic aerogels with high mechanical strength (E = 20 MPa) and remarkably low thermal conductivity (k = 21.9 to 28.9 mW/m·K).

Influence of Copper on the Hot Ductility of 20CrMnTi Steel

High Temperature Materials and Processes, 2014
Abstract The hot ductility of 20CrMnTi steel with x % copper ( x  = 0, 0.34) was investigated. Results show that copper can reduce its hot ductility, but there is no significant copper-segregation at the boundary tested by EPMA.
