To simplify the problem, the following assumptions are adopted: (1) The material is isotropic
Process parameters of laser cladding are shown in Table 1, the cladding materials on laser heat absorption rate of 30%.
Table 1 Process parameter of laser cladding Power [W] Scanning Velocity [mm/s] Spot Size [mm] 2000 3,4,5 5 2.4 Thermal properties of Co-based alloy Co base alloy material thermo-physical parameter is reference to similar composition alloy, and according to influence of elements, Co base alloy material thermal physical properties versus temperature curve are obtained by fitting.

This critical temperature increment can be considered a material constant.
It should be noted that the extension of this approach to other materials will require an initial calibration, similar to the one described above, for setting the critical temperature difference (∆T) that triggers failure by necking.

Introduction Lignocellulosic materials such as poplar wood have recently gained attention as feedstock for bioethanol production due to the limited supply and high cost of lignocellulosic sources from food such as corn [1–4].
Trichoderma reesei is widely used to produce cellulases for the conversion and utilization of lignocellulosic materials [5].
Materials and methods Fungal strain The parent strain, T. reesei Rut C30 (ATCC-56765), was previously stored by the Ministry of Forestry Bioethanol Research Center at the Central South University of Forestry and Technology (Changsha, China).
