Material Characterization

ObjectiveGenerate Data Bank on Chemical, Mechanical, Physical & Dynamic Properties o f Automotive Grade Advanced High Strength Steels (AHSS) &

Aluminum Alloys.

Significance

Increased environmental concerns are driving the auto industry to continual weight reduction of vehicles.

Advanced high strength steels (AHSS) enable weight reduction due to their higher strength and energy absorbing capacity.

Increased strain rates change the mechanical behavior of a material. It is important to study the high strain rate properties of the

materials to achieve optimum design, further weight reduction and safer vehicles

High strain rate properties (energy absorption, true s tress - true strain curves, strain rate exponent)

Fatigue properties (S-N Curve without stress concentration and with the Stress Concentration Factor of 2.5 & 4. Also E-N curves)

Microstructure and phase distribution

Texture analysis

Residual stresses

Materials Covered Include

Dual Phase (DP) steels

Bake Hardened (BH) steels

Interstitial Free (IF) steels

HSLA

Martensitic steels

Al-alloys emerging for body applications

New Facilities Established Include

PANalytical XPert PRO X-ray Diffractometer (Phase Identification and quantification, Retained Austenite, Texture, Residual Stresses)

Instron High Strain Rate Tes ting machine (65kN Capacity, max velocity 20m/s)
