Nanoindentation stress-strain for Fracture Analysis and computational modeling for hardness and modulus
A. S. Bhattacharyya, S Priyadarshi, S. Sonu +2
Stress-strain plots based on nanoindentation load-depth curves reflected cracking phenomenon. A transition from ductile to brittle fracture was observed on increasing the depth or…
Raman studies on nanocomposite silicon carbonitride thin film deposited by RF magnetron sputtering at different substrate temperatures
A. S. Bhattacharyya, S. K. Mishra
Raman studies of nanocomposite SiCN thin film by sputtering showed that with an increase of substrate temperature from room temperature to 500oC, a transition from mostly sp2 graph…
Nanocomposite si-c-n coatings
A. S. Bhattacharyya
Coatings of ternary nanocomposite Si-C-N ceramic coatings have shown newer and improved mechanical and functional properties over the coarser and monolithic coatings. Properties li…
Indentation of Coatings at micro/nano scale: Crack formation and deflection
A. S. Bhattacharyya
Nanoindentation is an effective way of finding mechanical properties at nanoscale. They are especially useful for thin films where elimination of the substrate effect is required.…
Substrate effect and nanoindentation fracture toughness based on pile up and failure
Arnab S. Bhattacharyya, R. Praveen Kumar, Rohit Mandal +4
The effect of substrate was studied using nanoindentation on thin films. Soft films on hard substrate showed more pile up than usual which was attributed to the dislocation pile up…
