In this paper, the high-strength water-soluble Na2SO4–NaCl composite salt cores (NNCSC)
strengthened by alumina powder using additive manufacturing 3D direct printing (3DP) …

This paper aims to improve difficult cleaning and high core requirements in castings with
complex internal cavities. The mixed salt was composed of NaCl, Na2SO4, BaCl2, and …

Conventional metal (sand) casting requires solid patterns consisting of two halves (cope and
drag) prepared to remove the pattern. The approach is simple but leads to numerous steps …

The work investigates the physical, mechanical, and technological properties of mixtures to
manufacture cores in a foundry. The filler is technical salt, the binder is an aqueous solution …

Parts with undercuts or hollow sections exploit the maximum lightweight potential due to
efficient material usage. However, such geometries are often challenging to produce with …

This paper presents a novel process for preparing high-strength water-soluble salt cores
with complex structure via layered extrusion forming using K2SO4 and KCl as the base salt …

In the process of pouring salt cores, it is crucial to select the appropriate mold temperature,
which is essential for the shaping and strength of the salt cores. Additionally, salt cores need …

In this paper, the interfacial energy of various inorganic salts was calculated using the first
principle. Finally, NaCl and Na2SO4 were determined as the core materials. A high-strength …

A composite inorganic salt core with good water solubility and formability was proposed
using potassium nitrate (KNO3) and potassium chloride (KCl) as base materials. The KNO3 …

A lightweight and high-strength water-soluble core mold for composites was prepared by hot-
air drying method using aqueous solution of polyvinylpyrrolidone as the adhesive and …
