In laser powder bed fusion, process-inherited thermal residual stress is developed due to the strain misfit between each layer. Detailed analysis and a prediction of are needed because it can induce distortions components and, in some serious cases, stress-induced defects such as cracking. this work, effects heat treatment conditions on maraging 18Ni-300 steel, fabricated by were investigated. ...

The nitrogen-vacancy (N-V) center in diamonds have the potential to be an ultra-sensitive magnetic field sensor that is capable of detecting single spins. Implementing this sensor for general and nontransparent samples is not trivial. For N-V centers to be a useful probe, a way of positioning the NV center with nanometer accuracy while simultaneously measuring its fluorescence is needed. Here, ...
