An input training dataset is needed to build a quantitative statistical learning model.Each material we are interested in must be characterized via a representation in terms of one or more material descriptors.The dataset used in this work consists of chemical composition,the raw materials’properties,processing parameters,and the green density information from several metal powders used for HVC,including Fe,Cu,an Fe-based alloy,an Al alloy,a Ti alloy,and a composite.The dataset comprises a total of 223 entries,as shown in Table 1,which were all collected from previous experiments in our laboratory on an HYP 35-2 HVC machine with a maximum capacity of 2 kJ per stroke,a maximum velocity of 10 m/s,and a hammer mass of 42 kg.
