Better performance in crash of AHSS compared to classical high strength steels is associated with higher work hardening
rate and high flow stress.
The lower stress predictions by both the models are the result of thermal softening and work hardening
effects at the shear plane.
The microhardness of the as-sprayed Ti coating was slightly higher compared to pure Ti bulk, owing to the work hardening
effect during deposition.
These cracks are a result of "work hardening
" brass, and annealing (heating and slow cooling) can extend brass life.
In addition, it will identify hard spots due to chemical changes, hydrogen enbrittlement and work hardening
The latter two assumptions imply that work hardening
in the material should not be significant enough to generate stable necking.
Most commonly seen when rough machining work hardening
materials such as stainless steels and high-temp alloys.
is another and, related, the impulses traveling through a spring exist well beyond the expected back-and-forth compression and rebound stresses.
Gerberich says that the surprising boost in hardness results from a familiar metallurgy process called work hardening
. It's normally achieved by operations such as hammering and rolling.
The sharp cutting edges and large conical front rake clearance reduce workpiece work hardening
. This new chamfer module uses two inserts, each with two cutting edges for increased productivity, economy, and security.
, induced by cold working the material, results in an increase in yield strength.
