When the Ti content was increased, a concave variation in the medium-thick-wall fluidity and a monotonic increase in the thin-wall fluidity were observed.
Medium-thick-wall fluidity depended on the heat release upon solidification of the alloy investigated, and thin-wall fluidity depended on the surface energy of the alloy in molten state.
The thin-wall fluidity and the HTS are both inversely proportional to the Mg content and directly proportional to the Si content.
Al 6Zn–(1.3–1.5)Mg–0.1 0.2 Ti–0.2)Ti alloys show 140 150% of ultimate tensile strength (370 390 MPa), 150 180% of elongation (10 12%), 60 80% of medium-thick-wall fluidity, and equivalent thin-wall fluidity, compared to the respective properties of the commercial A356 alloy.
By comparing to the physical and casting properties of the commercial ADC12 alloy, the developed alloys show 170 190% of thermal conductivities (160 180 W/m K), a similar medium-thick-wall fluidity, 60 85% of thin-wall fluidity, 100 130% of hot tearing susceptibility (HTS), and a comparable ultimate tensile strength.
Additionally, we examined asc1Δ sensitivity to hypotonic stress and to elevated temperatures, two stimuli that damage the fluidity of the cell-wall and activate the PKC signal transduction pathway [34], [35].
Changes in permeability and in membrane fluidity cause degradation of cell wall, a decrease in adherence to host's surfaces and variable effects such as disruption of cytoplasm membrane, leakage of cell contents, coagulation of cytoplasm and cell lyses [ 8, 9, 14, 17].
LPS plays an important role in the normal physiology, permeability and fluidity of the bacterial outer cell wall.
Molar ratios of the mycolic acid sub-types profoundly affect fluidity and permeability of the cell wall, as well as the immunological response in the host [11], [12], [28], [29].
