The present invention relates to improvements in processes for treatment of steel under a controlled atmosphere. Use is made of an atmosphere formed by a carrier gas comprising or containing industrially pure nitrogen and by an active gas formed by a hydrocarbon such as: CH4, C4H10, C3H8, C2H4...
Steel Heat Treatment: Equipment and Process Design presents the classical perspectives that form the basis of heat treatment processes while incorporating detailed descriptions of the latest advances since the 1997 publication of the first edition. This book covers the basic principles of heat treatment ...
2. Southwestern Aluminium Fabrication Plant, Chongqing 401326, P.R.China) Abstract:The triangular 2014 aluminium alloy forgings with intense strain were made by a variety of heat-treatment processes, and their mechanical properties were measured. The results showed that different solution and aging pro...
