TL;DR: In this paper, the corrosion behavior of two bulk glass-matrix composite alloys formed by copper mold casting was analyzed: Zr66.4Nb6.4Cu10.5Ni8.7Al8.0 with precipitated bcc dendrite phase and Zr57Ti8Nb2.5Cu13.9Ni11.1Al7.5 with quasicrystalline phase, respectively.
Abstract: The corrosion behaviour of two bulk glass-matrix composite alloys formed by copper mould casting was analysed: (i) Zr66.4Nb6.4Cu10.5Ni8.7Al8.0 with precipitated bcc dendrite phase and (ii) Zr57Ti8Nb2.5Cu13.9Ni11.1Al7.5 with quasicrystalline phase, respectively. The electrochemical behaviour was tested on the cross-sectional areas of the composite rod samples in 0.5 M sulphuric acid solution with up to 0.5 M sodium chloride addition by potentiodynamic polarization measurements. The composition of anodically formed passive films was studied by means of Auger electron spectroscopy (AES). The morphology of local damages generated by a chloride-induced pitting process was examined with scanning electron microscopy. In result of those studies, a pitting mechanism is described. For both composites in chloride media, a pronounced selective dissolution of the glassy matrix phase occurs, whereas the crystalline phases are not attacked. Niobium and titanium components are beneficial in inhibiting the pitting initiation due to their participation in the passive film formation. The dissolution of the glassy matrix phase is explained by the principal higher chloride reactivity of metastable phases compared to that of stable crystalline phases and by the detected enrichment of copper in these phase regions. The chloride attack progressing along the matrix phase causes the formation of deep channels in the bulk composite material leading to an excavation and, finally, detachment of the bcc dendrites or quasicrystals, respectively. The re-passivation ability is very poor.

TL;DR: In this paper, the thermal conductivities of three samples of titanium metal and for four titanium alloys were presented, together with values by Deem, Wood and Lucks 10 for titanium and six titanium alloy alloys.
Abstract: Values for the thermal conductivities of three samples of titanium metal and for four titanium alloys are presented, together with values by Deem , Wood and Lucks 10 for titanium and six titanium alloys. The lattice component of thermal conductivity of titanium metal is relatively large, and for this reason it is considered preferable to omit the parent metal when correlating the thermal conductivity, K, with the absolute temperature, electrical resistivity ratio, T ρ , of titanium alloys. The present results, expressed as J cm/cm2 sec°C, are then represented by the equation, K = 2.39 · 10 −8 T ρ + 0.0292 , and the present results, together with those of Deem et al., by K = 2.435·10 −8 T ρ + 0.027 . These properties are shown to be similar to those of zirconium and zirconium alloys.
