Web13 apr. 2024 · In this study, the tendency of having different grain structures depending on the impurity levels in AZ91 alloys was investigated. Two types of AZ91 alloys were analyzed: commercial-purity AZ91 and high-purity AZ91. The average grain size of the commercial-purity AZ91 alloy and high-purity AZ91 is 320 µm and 90 µm, respectively. … Web5 aug. 2024 · I think the problem has its origin in the expansion valve or the flash tank. These are modelled with the components "Receiver Accumulator (2P)" and Thermostatic Expansion Valve (2P)" respectively. In the case of the flash tank the BV port has no vapour mass flow even though there is vapour inside the tank, as shown in the picture.
