The high performance magnesium alloy was investigated by adding B2O3 in magnesium and magnesium alloys. Experiments include adding B2O3 in mg, mg-Al and mg-RE alloys, respectively, studying the effects of B2O3 on the microstructure, were studied measuring the change of grain size and microhardness of the materials, discussing the change of grain size, morphology and distribution. The results show that adding 3% or 6%(mass fraction) B2O3 in mg can bring twinning in mg, adding B2O3 in mg-Al alloys and mg-RE alloys can refine the alloy grain size. Adding 3%B2O3 in mg-6Al alloys can refine the average grain size by about 5μm, with the average hardness increased by 13.3% (53.3-60.4 HV0.03); adding 6%B2O3 in mg-6Al alloys can refine the average grain size by about 13μm, with the average hardness increased by 15.8% (53.3-61.73 HV0.03); adding 3% and 6%B2O3 into mg-6RE alloys can refine the grain size by about 5 and 9μm, respectively, with the average hardness decreased to HV0.03 64.66 and HV0.03 57.86, respectively from HV0.03 88.57. In the mg-6Al alloy the content of aluminum is increased, while in the mg-6RE alloy the content of oxygen is decreased. It can be concluded that it is beneficial to develop mg-Al-B-O particle reinforce composite alloys, and it is feasible to develop nanometer crystallization of block material by mg-B-O-RE.

Parthenogenesis is an asexual mode of reproduction that plays an important role in the evolution of sex, sociality, and reproduction strategies in insects. Some species of cockroach exhibit thelytoky, a type of parthenogenesis in which female offspring are produced without fertilization. However, the cytological and genetic mecha? nisms of parthenogenesis in cockroaches are not well understood. Here we provide the first molecular genetic evidence that cockroaches can reproduce through automixis. Using the American cockroach Periplaneta aniericana, we performed microsatellite analysis to investigate the genetic relationship between parthenogenetically produced nymphs and the parent virgin females, and found that all parthenogenetic offspring were homozygous for autosomal microsatellite markers, whereas the female parents were heterozygous. In addition, flow cytometry analysis revealed that the parthenogenetic offspring were diploid. Taken together, our results demonstrate that P. americana exhibits automixis-type thelytoky, in which diploidy is restored by gamete duplication or terminal fusion. These findings highlight the unique reproduction strategies of cockroaches, which are more varied than was previously recognized.
