Physical Features of Advanced Monocrystals Growth under Space Flight Conditions
Abstract: In terrestrial conditions, gravitational forces impede the production of materials with uniform distribution of components and phases. Strong thermo gravitational unsteady convection leads to instability of crystal growth parameters and limits the possibility of obtaining crystals with a high degree of homogeneity and structure with ideal parity. The first results of growing crystals under microgravity conditions showed the fundamental possibility of obtaining more perfect crystals due to the absence of …

Buckling Strength of Metallic and Composite Plates with Small and Large Hole at Different Locations
Abstract: Most of the aircraft structures will experience a buckling phenomenon due to compressive loads. The cutouts like system small and large holes, lighting holes etc. are introduced in the aircraft structure at different locations for accessing aircraft inside and for passing electrical wires and ducts. The stress rises around these holes due to removing area in the panel and buckling phenomena will become further critical in aircraft structures. The cutouts …

Kinematic Hardening Trend of Flow Formed Seamless Tubes of Aluminium Alloys used for Aerospace
Abstract: The current trend of making seamless tubes of aluminium alloys is flow forming. The strength, ductility and toughness are the properties of interest for proper alloy design of tubes to withstand combustion pressure from propellants, elevated temperature creep and stress corrosion, especially in marine environments. The final strength of the flow formed tubes is known to control these properties. Therefore, an efficient kinematic flow stress simulator has been formulated to …

Dynamic Hardness Trend of Tribological Steels Used for Advanced Power Transmission Assembly
Abstract: Gravity drop technique was used for measuring dynamic hardness trend of M50, 52100 and 4340 tribological steels. Work hardened state increased dynamic hardness, while shear bands and dynamic recovery of dislocations induced dynamic softening. Descending order of work hardening for the investigated steels is M50-52100-4340. The threshold strain to begin the softening gradually increases in the order M50-52100-4340 steels. Descending order of work softening beyond threshold strain for the investigated …
