What is science? Beyond Popper and Lakatos Why allowing non-falsifiable theories doesn’t make science soft and mushy Critics of the proposal, e.g. Stich Familiar construction kits Concrete and abstract construction kits Explaining what’s possible vs explaining what happens Historical note on "How is X possible?" Proving impossibility Eventual publication of the paper, in 1976, then as book-chap...

Nickel-based single crystal superalloy is the most important material for blade preparation. However, some solidification defects inevitably occur during process of preparing single-crystal blades through directional solidification. In this study, in order to study origin misorientation solidification, a model with rejoined platforms was designed according geometry guide vanes. Electron Back-Sc...

Abstract Growth rate is an important consideration in solidification as it influences features of the micro and macrostructure such morphology columnar to equiaxed transition. Thus, accurately quantifying growth key understanding process well verifying numerical simulations. In this work, experimental apparatus has been developed investigate in-situ directional using a transparent analogue mate...

Paraffin wax stores energy in the form of latent heat at a nearly constant temperature during melting and releases this solidification. This effect is used industrial storage. At same time, possible deformation even small volumes material as result phase change insufficiently studied. In paper, physical nature such deformation, probably for first studied on example droplet paraffin wax. An unus...

One of the most revolutionary aspects Laser Powder Bed Fusion (LPBF) is to be able lift design constraints from conventional manufacturing. However, as a rule thumb, any surfaces lower than 45° with respect horizontal plane would still require sacrificial supports in order complete printing. Fundamentally, it unclear whether feasible print 1st layer 0° overhang nor how parameters for can optimi...

Single-crystal rods with different diameters and deviation angles respect to the solidification direction were produced by Bridgman rapid method at withdrawal rates of 3 6 mm·min-1 used as grain continuators. The crystallographic orientation rods, which cross-sections perpendicular heights, was measured electron backscattered diffraction, while corresponding microstructures observed optical mic...
