【 摘 要 】

In our original paper, Acta Materialia 158 (2018) 430-439, we showed that adiabatic shear instability is not necessary for impact-induced jetting and bonding to occur in cold spray. We also developed a mechanistic framework to estimate the critical velocity for jetting on the basis of a hydrodynamic spall process. In their comment, Scripts Materialia xx (2018) xx-xx, Assadi et al. raised several questions about the versatility of our framework in capturing cold spray-related physical phenomena. Here, we demonstrate that not only can our mechanistic framework explain cold spray physical phenomena such as particle size effects, strength effects and temperature effects, but also it can be used to quantify them.
