Comparison of predicted hardness and experimental hardness of alloys 在5种合金中, Ni8合金拥有最高的硬度。图9中Ni8合金的XRD结果表明, B2相和FCC相的峰强相差较大, 说明两相含量相差较大, 更多的B2相导致合金具有更高的硬度。通过合金显微组织分析, 可以进一步揭示不同合金硬度差异的原因。图11为5种合金的...
LaMotte [cited in detail below] provides a helpful comparison between water hardness measurement using instruments and water hardness measurement using test strips:Instrument Measurement of Water Hardness: A colorimeter passes a white light beam through an optical filter which transmits only one particula...
